FixedLines
Visualizing a set of lines as cylinders (e.g., used to display characters)
Library
Modelica/Mechanics/MultiBody/Visualizers/Internal
Description
With model FixedLines a set of lines is defined
that are located relatively to frame_a. Every line
is represented by a cylinder. This allows to define simple shaped
3-dimensional characters. An example is shown in the
following figure:
The two letters "x" and "y" are constructed with 4 lines
by providing the following data for parameter lines
lines = {[0, 0; 1, 1],[0, 1; 1, 0],[1.5, -0.5; 2.5, 1],[1.5, 1; 2, 0.25]}
Via parameter vectors n_x and n_y a two-dimensional coordinate system is defined. The points defined with parameter lines are with respect to this coordinate system. For example "[0, 0; 1, 1]" defines a line that starts at {0,0} and ends at {1,1}. The diameter and color of all line cylinders are identical.
